Crazy water saving idea?

It took me about 20 gallons to cool my last batch. I used some in the washing machine and some in the water bath to cool the beer during primary.

I use pre-frozen jugs (which I reuse) in my pre-chiller. Run the water into the pool until it gets below 100deg then start to re-circulate with pond pump. All extra H2O goes into pool also.
